Definition 1. -
The T-carrier system, introduced by the Bell system in the US in the 1960's, was the first successful system that supported digitalised voice transmission. The original transmission rate (1.544 Mbps) in the Dearborn Heights T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
Definition 2. -
The T1 (or T-1) carrier is the most commonly used digital line in the United States, Canada, and Japan. In these countries, it carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). T1 lines use copper wire and span distances within and between major metropolitan areas. A T1 Outstate System has been developed for longer distances between cities.
Definition 3. -
A high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bits per second. A T1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a T1 is basically too large and too expensive for individual home use.
Definition 4. -
A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease T1 lines to connect to the Internet, but because they are expensive and offer more bandwidth than most small businesses and homes need, they are not realistic solutions for small and low-demand Internet users.

Dearborn Heights, Michigan, Sep. 23 /Don Romburgh/ --
Small businesses all over the country are discovering a whole new universe of broadband access.
As the price of commercial-grade telecommunication services continues to drop, more and more
enterprises are starting to drop their plain old telephone service lines in favor of all-digital
T1 trunks that deliver voice and data over the same connection. These new enhancements were
made possible by the increasing pace of consolidation in the telecommunication industry along
with the increasing value bigger phone companies can provide.
The same basic economic model described in the book "Blue Ocean Strategies" is now being
applied to telecommunication services being offered to small businesses across the country:
more value for less money. According to many industry watch dogs, hundreds of thousands
of business will dump their POTs lines in favor of dynamic integrated T1 service within
the next 12 to 24 months, saving money in the process. With the introduction
of sub-$475 dynamic integrated T-service, customers are now able to receive up to 1.5 MBPS
of high-speed Internet with 24 digital phone lines all on one line, for less than what they
pay now for 5 regular phone lines" Stallions continued.
The two basic Integrated T1 line configurations, as they exist in today's
market, are analog and digital. Commonly referred to as "trunks", these 24-channel
bundles transmit TDM signals directly to the service provider's network via a
local loop. Unlike analog trunks, whose configuration can not change once the
channels have been allocated, digital "dynamic" lines can change reconfigure
themselves from data, to voice, and back again. This ability to reclaim voice
channels for data broadband access when not in use gives the user the performance
of two T1's in one.
"True convergence means that I can finally have just one phone company, without being
at the mercy of Ma Bell" added Steven Lankto of Jersey City. "Having a data pipe that
is intelligent enough to know when it needs to become a voice pipe, without any input
from me, is genius. I'm glad that the technology is here and in the price range
of businesses like mine." Mr. Lankto isn't alone; there is now widespread acceptance
of integrated voice and data service in the New York metro area and across most
larger U.S. cities.
The irony of the new small business communications revolution is that it took so long
to gain traction. The whole idea of reclaiming inactive voice channels for data applications
is not new, and was introduced by many CLEC operators over five years ago. So why did
it take so long for SMB's to adopt the technology and make the change? One might argue
that the Internet bubble burst in 2000 shook many people's confidence in telecommunications,
one of the hardest hit industries. With so many telecoms going out of business, or merging
with other small players just to stay solvent, many customers took the "wait and see"
approach before making the decision to entrust their communications with a company not
associated with Ma Bell. Now that economic Darwinism has taken hold, the remaining companies
are attracting new customers who see the benefits of the new technology without the downside
risk of loosing service or not being able to get through to customer service in the pinch.
Integrated T1s comes in two basic configurations: digital and analog trunks, with a trunk
being a 24-line (or channel) bundle. The newer, digital trunks, however, are able to
run both voice and data over the same channels. By assigning priority to the voice
traffic whenever it is present, a dynamic integrated trunk can provide the end-user
with a full 1.5 MBPS of data throughput if no phone calls are in progress. As more
voice lines are required, less data lines are available. Analog trunks are all
pre-assigned to either voice or data traffic, and do not reconfigure in the event
there is no voice traffic.
CLECs are continuing to find new and loyal customers in the small business space, but
for how long will this trend continue? Will the RBOCs ever be able to give them a fight
on a level playing field? Only the FCC knows that answer to that question - all we can
do is be thankful for the past 12 years of progress and hope we never return to the
pre-1996 era of Telecommunications. Recent advances in technology, fostered by competition from growing CLECs, is bringing
integrated T1 services to small business everywhere. And the trend doesn't look like
it will change anytime soon. CLECs continue to grow their networks, offering more
advanced services like metro ethernet, MPLS, and more.
